The meeting edges of the strip 42 and the plates 26 and 28 are folded together as indicated at 44 and 45 and the meeting edges of the strip 43 and plates 27 and 29 are similarly folded together as indicated at 46 and 47 and these joints are preferably soldered in order to malte them oil tight. The respective ends ol the strip 43 are folded around the ends of the bracing structure as indicated at 48' amt-49 and the edg'es of the upper strip`42 are folded so as to rest upon the corresponding portion of the strip 43 as indicated at 50 and 51. The upper side of the. gear case may he provided `with a hinged door 52 in order that a suitable lu` bricant may be applied to the gears Without disinenibering the casing.

It will he understood from the foregoing description that the principal portions of the gear cases are of exceptionallythin, light weight metal and that the side plates of heavy metal that are riveted to the thin plates, are of suflicient rigidity to provide suitable supporting connections at the ends and to also preserve the form of the gear case under such strains as it may meet in service.

The form of the device and its structural details may, of course, he varied Within considerable limits without departing from my invention.

I claim as my invention.

1. A gear case for railway motors comprising a body portion, made up of thin metal plates, having their meeting edges :folded together and side plates of heavier metal riveted to the thin side plates.

2. A gear case for electric railway motors comprising side and edge plates of thin sheet metal, suitably fastened together at their edges and re-inforcing side metal riveted to the thin side plates.

3. gear case for electric railwa f motors comprising side and edge plates of thin sheet metal, fastened together at theirnin'eeting plates of thickeredges and side plates of heavier metal riveted to the thin side plates and having bent-.over end sections and re-inforcing hars or plates therefor.

4. A gear casing for electric railway motors comprising thin sheet metal sides and edge plates, having their meetingedgesfolded together and side plates of heavier metal riveted to the thin side plates and having reinforcing plates riveted to their ends.

A gear casing comprising side plates and top, bottom and end metal and side plates of relatively thick material riveted to the thin side plates. Y

6. A gear casing comprising four plane side plates and two curved plates l'or the top, bottom and ends, all voll thin sheet metal, and four re-inlorcing side plates of relatively thick material that are riveted tothe thin side plates. l A,

7. A gear casing composed ol: thin/'metal ripheral plates of sheet metal. and relatively thick and rigid re-inforcing plates that eX- tend along the adjacent edges of each pair of side plates and lool-.h edges of which are rivetedV thereto. f

1l. A gear casini! comprising edge plates of thin sheet meta and four side plates of thin sheet metal provided with a corresponding number ofrelatively narrovv re-intoreing plates of thick, rigid material that are riveted to thc respective thin plates adjacent to their contiguous edges. 4

in' testimony whereof, have. hereunto suhscrihed my name this `27th day of May, 1905 WILLIAM J. REICH.
